Preparing Your Receiver

Connecting Speakers

Follow these guidelines when you select and connect speakers.

Only connect speakers that are rated at between 6 and 16 Ohms.

Be sure you properly connect all speakers.

Do not connect two pairs of speakers to a single set of terminals at the same time.

Optimus and other high-quality speak- ers have color-coded speaker termi- nals (red for positive polarity and black for negative polarity). Use these color-coded terminals as a guide to help you properly connect the speak- ers to the receiver.

Use 16-gauge (or larger) speaker wire for all speaker connections, and con- sider possible speaker locations be- fore you decide how much speaker wire you need.

Preparing the Speaker Wires

Speaker wire consists of two conductors (individual wires) encased in insulation and is usually color-coded or marked with a ridge along one side so you can identify each conductor. Use these markings as a guide to help you properly connect the speakers to your receiver.

Follow these steps to prepare the speaker wires.

1.Cut the speaker wires to the necessary length.

2.Separate the wires about 4 inches on each end.

3.Using a wire stripper, carefully strip about 3/4 inch of insulation from the end of each conductor.

4.Twist the end of each conductor to secure any loose wire strands.

Setting the Impedance Selector Switch

Before proceeding to speaker connection, be sure to set the IMPEDANCE SELECTOR switch to the appropriate position. If you connect speakers with 6- to 8-ohm impedance, set the switch to 6~LESS THAN 8 W position. If you are using 8- to 16-ohm impedance, set it to 8~16 Ω position.
